But she soon discovered the real threats were not the people locked up there. What happened inside the Willacy detention center in South Texas was so disturbing it sparked 13 special criminal investigations by the Department of Homeland Security. Latino USA host Maria Hinojosa went inside the center, and deep into this case, in a segment produced by Catherine Rentz, in partnership with the PBS show FRONTLINE and the Investigative Reporting Workshop.
